Ribulose 1,5-bisphosphate (RuBP) is an organic substance that is involved in photosynthesis, notably as the principal CO2 acceptor in plants. [1]: 2 It is a colourless anion, a double …

2021年9月28日 · In the stroma, in addition to CO 2, two other chemicals are present to initiate the Calvin cycle: an enzyme abbreviated RuBisCO, and the molecule ribulose bisphosphate …

2023年4月7日 · RuBP refers to an organic substance that is involved in photosynthesis, notably as the principal CO 2 acceptor in plants, while RuBisCO refers to an enzyme present in plant …

2025年1月12日 · Ribulose-1,5-bisphosphate (RuBP) is a key molecule in photosynthesis, enabling plants to convert carbon dioxide into organic compounds. This transformation …

Rubisco catalyzes the incorporation of CO 2 into the 5-carbon sugar ribulose-1,5-bisphosphate (RuBP), yielding two molecules of 3-phosphoglyceric acid (3PGA). Based on the functional …

Ribulose-1,5-bisphosphate (RuBP) carboxylase-oxygenase (Rubisco) enzyme is the limiting step of photosynthetic carbon fixation, and its activation is regulated by its co-evolved chaperone, …

The enzyme ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) catalyzes the addition of CO 2 to ribulose-1,5-bisphosphate (RuBP), which is quantitatively the most significant …

RuBP (ribulose 1,5-biphosphate) is a five-carbon sugar which reacts with CO 2 in the first step of the Calvin cycle for fixing carbon in photosynthetic systems. That reaction is catalyzed by the …

Ribulose bisphosphate (RuBP) is consumed in the carboxylating step of carbon fixation. If such fixation is to continue, RuBP must be regenerated, and in this case via the PCR cycle.

2023年5月25日 · Carboxylation of ribulose-1,5-bisphosphate (RuBP) is the first step in the Calvin-Benson-Bassham (CBB) cycle, which requires the activation of Rubisco through carbamylation …
